Definitions
- This invention relates to an apparatus for intimately contacting particulate solids with a heavy liquid.
- This invention further relates to an apparatus for intimately contacting dried particulate low rank coal with a heavy oil.
- an apparatus for intimately contacting particulate solids with a heavy liquid comprising:
- a particulate solids inlet means in communication with an upper end of the contacting vessel and positioned to discharge a stream of particulate solids downwardly into the upper end of the contacting vessel;
- a generally conical deflector means having an outer diameter less than an inner diameter of said contacting vessel and positioned in the contacting vessel and beneath the particulate solids inlet to deflect the stream of the particulate solids outwardly over an outer diameter of the deflector means;
- an inlet control means operatively associated with the particulate solids inlet means to control the flow of the particulate solids into the contacting vessel and prevent the discharge of gaseous materials from the contacting vessel through the particulate solids inlet means;
- a particulate solids outlet means in communication with the lower end of the contacting vessel and positioned to discharge a stream of particulate solids from the contacting vessel;
- an outlet control means operatively associated with the particulate solids outlet means to control the flow of particulate solids from the contacting vessel so that a bed of particulate solids is maintained in a lower portion of the contacting vessel so that gaseous materials are exhausted from the contacting vessel through the bed of particulate solids;
- spray means positioned in the contacting vessel to spray the heavy liquid onto the particulate solids as the particulate solids fall downwardly to the bed of particulate solids, the spray means being positioned so that no spray is directed toward the inner walls of the contacting vessel.
- FIG. 1 is a schematic diagram of an embodiment of the apparatus of the present invention
- FIG. 2 is a top view of the apparatus shown in FIG. 1;
- FIG. 3 is a schematic diagram of an embodiment of a method of controlling the discharge of particulate solids from the apparatus shown in FIG. 1.
- FIG. 1 a contacting vessel 10 is shown.
- Particulate solids to be treated in vessel 10 are charged to vessel 10 through an inlet 12 which includes a control means 14 for regulating the flow of particulate solids into vessel 10.
- control means 14 is a metering valve such as a star feeder or the like which permits the flow of particulate solids through line 12 into vessel 10 at a controlled rate while preventing the escape of exhaust gases from vessel 10 through line 12.
- a deflector 16 is positioned in vessel 10 and generally directly beneath the discharge from inlet 12. Deflector 16 is a generally cone shaped member which may be supported in position by any convenient means such as by support members in contact with the inner walls of vessel 10 or the like.
- Suitable methods for supporting deflector 16 are considered to be well within the skill of those in the art and no novelty is considered to reside in the particular method chosen for mounting deflector 16.
- An outlet 18 shown as line 18 in FIG. 1, is provided for the discharge of treated particulate solids from vessel 10.
- the flow of particulate solids from vessel 10 is desirably regulated to maintain a bed of particulate solids 22 in vessel 10. Desirably the bed of particulate solids is maintained at a level to be discussed hereinafter.
- the bed of particulate solids maintained in vessel 10 serves to filter the exhaust gases discharged from vessel 10 by passing the discharged gaseous materials downwardly through bed 22 and out of vessel 10 via line 18.
- the level of bed 22 in vessel 10 may be maintained by the use of a loosely fitted metering valve 20 such as a star valve adapted to permit the flow of gaseous material therethrough, the use of a throttle plate or the use of a belt conveyor positioned beneath a discharge chute positioned on the bottom of vessel 10 as disclosed in U.S. Pat. No. 4,547,198.
- a loosely fitted metering valve 20 such as a star valve adapted to permit the flow of gaseous material therethrough
- a throttle plate or the use of a belt conveyor positioned beneath a discharge chute positioned on the bottom of vessel 10 as disclosed in U.S. Pat. No. 4,547,198.
- FIG. 3 is a schematic diagram of an embodiment of the use of such a conveyor belt.
- Discharge 18 is positioned a short distance above a conveyor belt 32 which is of a width suitable to maintain particulate solids in discharge 18 and vessel 10 above belt 32 as a result of the angle of repose of the particulate solids.
- the belt should be of a sufficient width to prevent the spillage of particulate solids over the sides of the belt and the rate of withdrawal of particulate solids from vessel 10 is determined by the rate at which belt 32 is passed beneath discharge 18.
- a plurality of spray nozzles 24 and 26 are positioned in the upper portion of vessel 10 to spray a heavy liquid such as a heavy oil onto the particulate solids charged to vessel 10 through inlet 12.
- particulate solids are charged to vessel 10 through inlet 12 and passed downwardly into vessel 10 where the particulate solids fall onto the surfaces of deflector 16 and pass outwardly over the outer diameter of deflector 16 and fall into bed 22.
- Spray nozzles 24 and 26 are positioned to spray a heavy liquid directly onto the falling particulate solids.
- at least two sets of spray nozzles are used. As shown in FIG. 2, it is desirable that an outer set 26 of spray nozzles and an inner set 24 of spray nozzles be used.
- the use of at least two sets of spray nozzles allows the removal of one set of spray nozzles at selected intervals for cleaning, replacement and the like without disruption of treating operations.
- Spray nozzles 26 are selected and oriented to spray a cone pattern 30 of spray onto the falling particulate solids. It will be noted that pattern 30 does not result in the spraying of heavy liquid onto either the walls of vessel 10 or deflector 16. In the event that there is overspray, i.e. not all the sprayed heavy liquid strikes the particulate solids, the overspray strikes the surface of bed 22. As a result, the heavy liquid all strikes particulate solids.
- the level of bed 22 is desirably maintained at a level such that the spray pattern from each of the sets of spray nozzles strikes the surface of bed 22.
- sprays 24 are selected and adjusted to spray a cone pattern 28 which is similar to the cone pattern 30 sprayed by spray nozzles 26.
- the apparatus of the present invention is particularly well adapted to the treatment of dried low grade particulate coal with heavy oil.
- Any suitable heavy oil can be used with some suitable heavy oils having been disclosed in U.S. Pat. No. 4,201,657 and U.S. Pat. No. 4,402,707 previously incorporated by reference. These oils are illustrative of suitable oils but the invention is by no means limited to such oils although heavy oils are a preferred treating material for the treatment of dried particulate low rank coals.
